I don't know what you mean by that exactly?? I disable all vbanking, as it's only really required if you see screen tearing, which I have never seen on any of the monitors that I have used..

He probably means, that when using virtual refresh syncing you have to have some framerate that is divisable into 75 to not have tearing, which means you can either have 75/1=75, 75/2=37.5, 75/3=25, 75/4=18.75, 75/5=15, and so-on.

exactly. One big difference is that under windows the actual screen refresh are 60Hz but under linux it's 75HZ. This alone could result in animation that looks like they jump on the screen as quake4 want to update only 60Hz.

I did some more testing and it's possible to setup windows to behave in the same way as in linux by changing the global defaults. my big problem now is how do I translate the good windows settings to linux ??

I know D3 has that 60 FPS limit, but does that mean that vsync has to be enabled? does performance change when vsync is disabled?

I have vsync disabled in all the games I play.. My monitor is synced to 85Hz refresh, where as D3/Q4 are 60Hz (You can change that, but it will change the WHOLE game play), and I don't see any problems with vsync disabled. *shrug* . With it disabled, it will increase the games performance, as it doesn't have to wait for Vsync before the data can be sent to the display. If you get the 63fps lock, then the only thing you may notice, is that D3 will respond a little better. (That's what I've noticed). In most cases, if you experiance screen tearing, then enabling vsync will fix that. Depending on ones hardware, you most probably won't notice much difference. (on high performance systems) When running the timedemo test in D3, with vsync off, I usually notice a 5-15fps increase. A 5fps increase in certain stituations in the game can help alot. Especially when there's alot of action.

I managed to get hold of an MSI NX8800GTX to test over the weekend. Here is my findings with this card so far.. (Nvidia-Settings see's it as a G80-300) Idle temp 60degrees C (NX7900GTO idle temp 37-40Degrees C)

Both D3 & Q4, contstant 60-63fps locked. (Same as my NX7900GTO) (I run all my games @1280x1024 when possible)

The only problem I've found with the 97.42beta drivers, is that I can't set the AA in Q4 to 16x. When I do, Q4 won't run at all, I need to drop it down to 8x AA to get it to run. (D3 is fine though ) Both have all the latest patches.

1) you need a higher resultion to to see what yout 8800GTX is capable of....
2) try setting it in the driver; the in game setting in doom3/quake4 never changed anything for me (image and perfomance)

Doom3 - 6 passes of timedemo. varies between 94.3-97.5fps (Same settings except resolution increase) @ 1600x1200.. I see no improvement.. This of course can still be related to the beta driver.. (Most 19" LCD monitors won't go above 1280x1024. Unless one has a larger display. So one should see some performance boosts at that resolution)

I've set both the driver (for X) and the game to 1600x1200.. (All other settings are unchanged)

Hi,
I also performed some speed tests(not quake 4) but I have to say that currently the card's power under linux is often not even half the power of a 7800.
I guess the drivers are currently really not ready.
Under windows the card is MUCH faster than the 7800.

The only thing that seems to work is the better branching capacity.

I guess all your problems (and mine ...) will be solved with the next driver release.
